Mark Deklin and his wife Jamie just welcomed another member to their family, and he is way tooooo cute!!

The GCB/Lone Star actor's wifey gave birth to 7-pound Julian Ryder earlier this month at the Good Samaritan Hospital in El Lay, which marks the couple's second kid — as they're already parents to a 3-year-old girl, Kylie.

Deklin and Jamie revealed:

“We were curious to see how our 3-year-old would react to her new little brother, and it turns out that she couldn’t be more in love. So far our biggest problem is that she wants to hold him ALL the time. It’s really beautiful to watch.”

A new life is always AH-MAYZING!

We're glad Kylie loves her little bro 'cuz we know how sometimes the former baby can get jealous of a newborn child.

But in this case, it seems like all the toddler wants to do is ADORE her new sibling!!
